Simulation and Modelling of Particulate Systems

Particle science and technology is a rapidly developing interdisciplinary research area with its core being the understanding of the relationships between micro- and macro-scopic properties of particulate/granular matter – a state of matter that is widely encountered but poorly understood. The macroscopic behaviour of particulate matter is controlled by the interactions between individual particles as well as interactions with surrounding gas or liquid and wall. Understanding the microscopic mechanisms in terms of these interaction forces is therefore key to leading to truly interdisciplinary research into particulate matter and producing results that can be generally used. This aim can be effectively achieved via particle scale research based on detailed microdynamic information such as the forces acting on and trajectories of individual particles in a considered system. In recent years, such research has been rapidly developed worldwide, mainly as a result of the rapid development of discrete particle simulation technique and computer technology.

Thistalk presents a brief overview of thetheoretical developments indiscrete element modelling. It covers three important aspects: models for the calculation of particle-particle and particle-fluid interaction forces under different conditions, coupling of discrete element method with computational fluid dynamics to describe particle-fluid flow, heat and mass transfer, and the theories for linking discrete to continuum modelling. Focus is however given to thosedeveloped in my laboratory for Simulation and Modelling of Particulate Systems “SIMPAS”. It is also demonstrated through examples that the study of small particles is well linked to many challenging problems in big science.The examples also demonstrate that particle scale approach has gradually emerged to be a powerful tool not only for fundamental research but also for engineering application.Needs for future development are also discussed.

Brief Biography

Professor Aibing Yu specialized in process metallurgy, obtaining BEng in 1982 and MEng in 1985 from Northeastern University, PhD in 1990 from University of Wollongong (UoW), and DSc in 2007 from the University of New South Wales (UNSW). Heis currently Vice-Chancellor’s Professorial Fellow, Pro Vice-Chancellor and President of Monash Suzhou, Monash University. He has been Inaugural Director of UNSW Centre for Simulation and Modelling of Particulate Systems, Deputy Director of ARC Centre of Excellence for Functional Nanomaterials, Founding Director of Australia-China Joint Research Centre for Minerals, Metallurgy and Materials, ARC Research Hub for Computational Particle Technology, and JITRI Research Institute for Process Modelling and Optimisation. He is also Chair, Technical Advisory Committee of Baosteel-Australian Universities Joint R&D Centre.

He is a world-leading scientist in particle/powder technology and process engineering. He has made many significant contributions and is recognised as an authority in particle packing and flow, particulate and multiphase processing, and simulation and modelling. He has authored/co-authored >1,000 publications (including >650 collected in the ISI Web of Science), delivered many invited plenary/keynote presentations at various international conferences, and graduated >40 postdoc fellows and >100 PhD students. He is Editor of Powder Technology, Regional Editor of Granular Matter, and on the editorial board of ~20 learned journals.

He is a recipient of numerous prestigious awards/fellowships including ARC Australian Professorial and and Federation Fellowships, Josef Kapitan Award from Iron and Steel Society (ISS), Ian Wark Medal from Australian Academy of Science, ExxonMobile Award from Australian and New Zealand Federation of Chemical Engineers, NSW Scientist of Year in the category of engineering, mathematics and computer science, and the Top 100 Most Influential Engineers in Australia. He was elected to Fellow of the Australian Academy of Technological Sciences and Engineering (ATSE) in 2004, and Australian Academy of Science (AAS) in 2011, and Foreign Academician of Chinese Academy of Engineering (CAE) in 2017.
